Abstract:
A multilayer coating includes a bond coat layer, a first barrier layer applied on the bond coat layer, and a second barrier layer applied on the first barrier layer. The first barrier layer has a compositional gradient comprising a majority of a first rare earth stabilized zirconia material proximate the bond coat layer to a majority of a second rare earth stabilized zirconia material away from the bond coat layer. The first and second rare earth stabilized zirconia materials are different. The second barrier layer has a compositional gradient comprising a majority of the second rare earth stabilized zirconia material to 100 wt % of a third rare earth stabilized zirconia material away from the first barrier layer.
